BACKGROUND The objective of this study was to clarify the usefulness of positron emission tomography (PET) using(18)F-fluorodeoxyglucose (FDG) and carbon 11-labeled acetate (AC) for predicting the histologic types and tumor invasiveness of thymoma in a multicenter study. METHODS Forty thymomas were examined using both FDG-PET and AC-PET before surgery.(More)
PURPOSE The aim of this study is to clarify characteristics of invasive breast cancer with expression of Hypoxia-induced factor 1alpha (HIF-1alpha) which is induced by hypoxia and signal transduction of growth factors. EXPERIMENTAL DESIGN We examined, by immunohistochemical analysis, the expression of HIF-1alpha in normal breast tissue, benign disorders(More)
BACKGROUND To examine whether segmentectomy is radical for cT1N0M0 non-small cell lung cancer (NSCLC), a prospective single-arm study was performed at a single institution. METHODS The criteria for segmentectomy were as follows: (1) peripheral-type cT1N0M0 NSCLC; (2) intraoperative frozen sections of sentinel nodes identified with isotope showing no(More)
We present the cases of 3 children with huge undifferentiated sarcoma of the liver who were treated with surgical excision including liver transplantation as an option and adjuvant chemotherapy. All 3 patients were males aged 10, 13, and 15 years old. The size of the tumor was 10, 15, and 20 cm in diameter, respectively. The youngest patient is disease free(More)
OBJECTIVES Although positron emission tomography (PET) using F-fluorodeoxy-glucose (FDG) frequently gives false-negative results for slow-growing tumors, C-acetate (AC)-PET has been reported to be able to detect them. To determine the usefulness of AC-PET for imaging non-small cell lung cancers (NSCLCs), the sensitivity and specificity were compared between(More)
A solid pseudopapillary tumor (SPT) of the pancreas is a rare neoplasm that mainly occurs in young women. We herein report the case of a small SPT arising from the head of the pancreas in an asymptomatic 32-year-old man, plus a literature review of this tumor. A 32-year-old man was admitted to our department at Kumamoto University Hospital for the(More)
OBJECTIVE This study aims to assess the role of three-dimensional single-photon emission computed tomography (3D-SPECT/CT) in sentinel node (SN) identification, and to analyze the impact of such information on estimating metastases to SNs. BACKGROUND Nodal status is a key factor for breast cancer. SN biopsy has been established as the alternative to(More)
Hairy cell leukemia (HCL) is occasionally misdiagnosed as aplastic anemia when only a few leukemic cells are present in the circulation. Here, we describe a patient with HCL who initially presented with pancytopenia and received a diagnosis of aplastic anemia. The patient was treated with immunosuppressive therapy including cyclosporine A and anti-thymocyte(More)
BACKGROUND This study was performed to clarify the influence of preoperative chemotherapy on liver function and the correlation between histological hepatic injury and the postoperative outcome in patients with colorectal liver metastases who underwent a hepatic resection. METHODS Twenty-seven patients who underwent a hepatic resection for colorectal(More)
CD138 expression is a hallmark of plasma cells and multiple myeloma cells. However, decreased expression of CD138 is frequently observed in plasma cells of myeloma patients, although the clinical significance of this is unclear. To evaluate the significance of low expression of CD138 in MM, we examined the phenotypes(More)
